Abstract:
The existing scientific investigation is made of 20 genotypes of Black gram which includes one check. Data were collected for 13 traits to examine the Genetic variability, heritability, correlation, and direct as well as indirect impacts of yield-related factors in the different genotypes of Black gram. Based on the mean overall performance genotype KU 96-1 Followed by NO-766843, IPU-99-40.The following genotypes have been identified as outstanding candidates for achieving a high yield of seed per plant. Substantial and statistically crucial variations were observed across all the studied characteristics. Heritability estimates were significantly observed for various traits, including the height of the plant and seed index. The high values indicate that the considerable contributions of genotypic components play a crucial role in determining traits. The harvest index displayed a notable increase in genetic advance compared to the mean. Traits with peak heritability and a substantial genetic gain indicate the action of additive genes principally on these traits. Both simple gene action and interaction gene actions make equal contributions to the overall manifestation of these traits. The study conducted unveiled an optimistic and remarkable association between the yield of seed by plant and several factors, including the no of plant clusters, no of pods per plant, length of the pod, seed count by pod, total dry mass yield, and yield efficiency. Structural equation modeling at each phenotypic level and genotypic level recognized no of main branches per plant, total dry mass yield, and yield efficiency are crucial direct factors influencing seed yield per plant.
